In solar vacuum tube collectors, the insulating effect is achieved by a vacuum in a glass tube or the space of two concentric glass tubes. Evacuated tube solar collector absorbs part of the solar radiation which strikes the outer glass tube. The radiation crosses the vacuum space between the outer and inner pipe without energy loss.
However, the growing demand of solar energy and modern manufacturing techniques has driven down the cost such that vacuum tube technology can provide great return on investments for applications requiring high temperatures. The principle behind solar vacuum tubes is simple. A solar vacuum tube works similar in design to a coffee thermos.
Evacuated tube solar collector absorbs part of the solar radiation which strikes the outer glass tube. The radiation crosses the vacuum space between the outer and inner pipe without energy loss. Finally, solar radiation heats the working fluid inside the inner pipe and vaporizes it.
